A grieving man trapped inside a time-shifting house discovers that each room reveals not only his own past and possible futures, but the lives of other tenants who have lived—or will live—there. Guided by an ageless "Builder" who offers him godlike control over the house’s dark design, he refuses the offer, only to realize that escape was an illusion and the prison has chosen someone he loves as the next occupant.

SYNOPSIS:

Concept Summary:

Summa Tenebris is a psychological supernatural thriller about grief, regret, and the seductive allure of control. Inside a mysterious, century-old house, every room functions as a portal to a different time—past, present, or possible future—not just of the protagonist, but of every person who has ever lived, or will live, in the house.

The house is governed by the ageless Builder, who has been managing its darkness for over a century. Each timeline he encounters reveals both beauty and horror: the protagonist sees his own family’s alternate lives, but also glimpses the lives of previous tenants—their joys, betrayals, and tragedies. The Builder offers him godlike authority over the house’s dark design, tempting him to master the prison. But when he refuses, the house recalibrates—the weight of the prison shifts to someone he loves, revealing that the cycle is eternal.

This story explores the moral cost of attempting to control fate, the weight of grief, and how suffering can be harvested across generations. The house becomes a character itself: a vast, living system of memory, desire, and consequence.
